Description of key information
Not readily biodegradable: 14% (DOC) in 28 days (OECD 301B)
Key value for chemical safety assessment
Additional information
The ready biodegradability of Dipentaerythrol ester of nC5/iC9 acids was investigated in a CO2 evolution test using activated sludge from a waste water treatment plant treating predominantly domestic sewage (Mead, 2000) according to OECD 301B guideline and GLP. The test substance attained 14% degradation after 28 days and was therefore identified as not readily biodegradable according to OECD criteria. The test was accompanied by a reference control (100% degradation after 28 days) and a toxicity control (41% degradation after 28 days) which confirmed the suitability of the inoculum and test conditions and met the requirements of the guideline.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
